ADK KOMATSU (P81) Fittings

Straight KOMATSU fittings with external thread and 60° cone 

P81 ADK straight fittings with metric external thread - with external 60°  degrees (convex cone). The fittings are suitable for connecting with metric fittings with a nut, i.e., P91 DK KOMATSU - after tightening they create a tight high-pressure connection.

P81 JIS ADK fitting.

ADK KOMATSU (P81) fittings are hydraulic fittings,  which are part of hydraulic systems used in construction and industrial Komatsu machinery and other equipment compliant with Japanese standards. They are characterized by a 60º cone seal and metric threads, providing durability, tightness and reliability in high-pressure hydraulic systems. Where are ADK fittings used ? Hydraulic systems of Komatsu machines: ADK fittings are dedicated for use in Komatsu equipment, including excavators, loaders and other heavy machinery. Power hydraulics applications: Ideal for high-pressure connections in control and drive systems. Industrial and construction machinery: Used in hydraulic systems where a connection compliant with Japanese standards is required. Industries: Construction: Komatsu machines, excavators, dozers, loaders. Heavy industry: Material handling equipment and machine hydraulic systems. Agriculture: Tractors and combines using Japanese hydraulic standards. Transport: Vehicles with hydraulic systems requiring compatibility with JIS standards.
